What type of medication is Tudorza Pressair?

Tudorza Pressair is classified as a Long-Acting Muscarinic Antagonist (LAMA). It contains the active ingredient aclidinium bromide, which works by blocking the action of acetylcholine at muscarinic receptors in the airways. This action results in relaxation of the bronchial smooth muscle, leading to dilation of the airways and improved airflow in individuals with chronic obstructive pulmonary disease (COPD).

LAMA medications are particularly important in the management of COPD because they provide prolonged bronchodilation, which helps relieve symptoms and improve lung function. This differentiates them from other classes such as Long-Acting Beta-Agonists (LABA) and Short-Acting Muscarinic Antagonists (SAMA), each of which has different mechanisms of action and indications for use. Antibiotics are unrelated to the treatment of COPD symptoms, as they are used to treat bacterial infections, not for bronchodilation or managing chronic respiratory conditions.
